Detectomat M4-RS485-Module Control Unit Serial Communication Interface Card

This module is an interface card that establishes data exchange between the control unit and external devices over the RS-485 line. This serial data path, known for reliable operation over long distances, is frequently chosen when connecting to building automation and monitoring systems. The card is installed in the control unit enclosure, providing the system with an additional communication channel. Different disciplines are able to share the same event information through this connection.
